tom of the hole so that the front overlaps the hole by 5
mm at the bottom. Connect the appliance.
Make a rectangular hole of incombustible and heat-resist-
ant material (e.g. promatec)

Lift the front panel out of the brackets. Remove the box of
logs and the bag of accessories from the combustion
chamber by opening the glass front.To do this, unscrew the
two socket-head bolts on the right of the glass, using the

Packing
socket-head spanner provided. Lift the glass out of the
brackets and position the heater as required.There should
be a little space all round the appliance in the fireplace to
allow the heat to escape; if this is not possible fit a convec-
tion connection set, available as an accessory from your
dealer.The heater can also be installed in a corner, see fig. 1
for the space this requires.
Mantel iron
An L-shaped mantel Iron can be ordered from your
installer.The mantel Iron, intended to support the brick-
work above the fire.This enables a stress-free installation
of the appliance. Fit the mantel iron as illustrated in fig. 2,
685 mm high and 620 mm wide

INSTRUCTIONS FOR INSTALLATION
allowing 5 mm between the top of the appliance and the
bottom of the mantel iron, so that the packing cord pro-
vided seals adequately. Make sure that the front of the
heater (without the decorative facing) and the front of
the mantel iron are flush. Fitting the decorative facing will
hide the mantel iron from sight.

Convection connection

The convection system of flexible pipes will enable the
heat to be spread to every corner of the room.The con-
nection materials can be ordered separately from your
dealer.
Possible connections (fig. 3)
The external duct can pass through either the wall or the
roof; the connections to both supply and flue pipes
should meet the following requirements:
• The first metre of pipe should always be installed
vertically.
• The horizontal length of pipe must never exceed 4 metres.
• The maximum length of vertical pipe is 12 metres.
Allow 2 metres for a bend of 90° and 1 metre for a 45°
bend.There is no need to allow for the length of the wall
or roof duct.
The maximum total length is the sum of the pipe lengths
plus the equivalent length for the bends (see the four
examples in fig. 3).
The roof duct set, the supply and flue pipes, the concen-
tric pipe and bends are packed individually and supplied
together with a clip binding with sealing ring.Tile flashing
or adhesive flashing is also available for use with a duct
through a slanting or flat roof respectively.
NB: This appliance may only be installed using the flue
material ø150/ø80 supplied by DRU.This has been
approved together with the appliance to comply with all
requirements. DRU cannot guarantee that the appliance
will work correctly and safely if alternative installation
material is used.
Preparations for the installation of the com-
bined inlet-outlet system
• Select the required connection from the options shown
in figure 3.
• Erect the concentric pipes from the heater up. If the
structural situation requires that the first section of the
concentric pipe system be built in, take special note of
the required method of assembly.
• The appliance has a coupling section; fit the first metre
of pipe onto this.
• Allow at least 5 cm between the outside of the concen-
tric pipes and the wall or ceiling.

Wall duct with concentric pipes

Ensure that the first metre of pipe used for the wall duct
is assembled vertically.
• Determine the position of the appliance and the position
